Update for Thursday night:
Quiz tomorrow. Tonight, study vocab and Bikini Bottom or other Punnett Square worksheets.
All classes: Homework tonight is to work on Bikini Bottom Genetics 2 (1st page only). 

Friday's Quiz will be on:
1. Genetics concepts such as
* Dominant vs. Recessive,
* Phenotype vs. Genotype,
* Heterozygous vs. Homozygous;

2.  How to use Punnett Squares to find the possible results of pairing two parents with a certain trait, and the probability, or chances, of each trait appearing in each offspring. 

3. Vocabulary, copied below.  You should have all of these terms in your science notebook (if not, now is a good time to add those definitions to your vocab section).  Don't forget: you were to draw out 8 Frayer Diagrams, using vocab words. I f you didn't already do it, do it now and show me your work tomorrow:

Phenotype - organism's observable traits (what you can see on the outside).

Genotype - individual's pair of alleles for a specific gene or group of genes that determines a trait (what's in the genes).

Dominant - version of gene that appears with only one copy of a version of a gene (an allele).

Recessive - hidden trait, that is, the genetic trait that is not observed in a heterogeneous individual.

heterozygous - an organism that has more than 1 kind of allele for a characteristic. 

homozygous - an organism that has only one kind of allele for a characteristic.

Punnett Square - diagram to show the likelihood of each outcome of a breeding experiment with known parent genes for a trait. See p. D-37.

Characteristic - an observable or measurable feature of an organism and may be caused by one gene or many genes. Ex: eye color.

Gene - A specific sequence of DNA that determines one or more traits.

Allele - a variant or version of a gene. Ex: a gene could code for a round thumb joint, or a squared off thumb joint. One is Dominant (it wins), while the other is Recessive (it loses unless its the only one).
Genetics is the study of the location and behavior of genes, their passage to offspring, and of how characteristics are inherited.
Heredity - traits passed down to people or other organisms from their biological parents. Ex: eye color, tongue rolling, height potential, genetic diseases, arm span.

Inherited - The passage of traits from parent to offspring.

Hybrid: is an offspring of two animals or plants of different breeds, resulting from the breeding of two genetically distinct individuals .  Ex: Tiger + Lion = Liger.  The Liger is a hybrid.

The opposite of Hybrid is Purebred.
